Google应用程序引擎的Python API问题

我的API遇到问题，无法创建用户记录/将其存储在Google数据存储中。我收到下面列出的JSON响应

另一件我觉得奇怪的事情是，当使用位于右上角的GoogleAPIsExplorer时，它有一个红色感叹号，表示方法需要授权。它希望我为用户电子邮件授权OAUTH作用域

更新：这是我通过GAE获得的错误日志

我刚刚意识到这一点。我对后端工作和python比较陌生。谢谢你的帮助，真的很快。存储实体后，如何返回该实体。我希望响应是被存储用户的JSON。return UserCreateResponseMessageemail=request.email，password=request.password上面定义的UserCreateResponseMessage有三个字段——email、username和id，因此您必须设置它们；它没有密码字段-这只是在请求中。很抱歉，我实际上是在处理一组不同的消息。这仍然帮助解决了我的问题。谢谢，我才意识到这一点。我对后端工作和python比较陌生。谢谢你的帮助，真的很快。存储实体后，如何返回该实体。我希望响应是被存储用户的JSON。return UserCreateResponseMessageemail=request.email，password=request.password上面定义的UserCreateResponseMessage有三个字段——email、username和id，因此您必须设置它们；它没有密码字段-这只是在请求中。很抱歉，我实际上是在处理一组不同的消息。这仍然帮助解决了我的问题。非常感谢。
